John Baker (c. 1754 - 20 January 1831) was an English Whig politician who sat in the House of Commons of Great Britain and of the United Kingdom in 1796 and 1797 and from 1802 to 1818.
He lived at Hawkhurst Lodge, in the Weald of Kent, and became one of the largest hop-planters in the district.
In 1796, Baker was elected Member of Parliament for Canterbury on what was called the independent interest.
He headed the poll with 774 votes but the election was declared void on petition under the provisions of the Treating Act.
At the second election in March 1797 he again had a majority of votes, "although not one public-house had been opened in their interest, nor a single cockade distributed".
